Orbital velocity but not orbital trajectory.

Velocity is a vector, so it would be more proper to say "orbital speed". But no one does that.

Vectors are location independent, so theoretically any velocity with sufficiently high speed would be orbital velocity even if it was pointed directly at the planet, no?
